The amount of movement, linear momentum, momentum or momentum is a physical quantity derived from a vector type that describes the movement of a body in any mechanical theory. In classical mechanics, the amount of movement is defined as the product of body mass and its velocity at a given time.
p= mv
Where,
m = mass
v = Velocity
Our values are given as,
Replacing we have that,
Therefore the momentum is
Answer:

Answer:
The velocity of Dan is 1.13 m/s.
Explanation:
Given that,
Initial velocity of skateboard and Dan = 2.00 m/s
Velocity of skateboard = 7.00 m/s
Mass of Dan m= 40.0 kg
Mass of skateboard M= 7.00 Kg
Suppose How fast is Dan going as his feet hit the ground?
We need to calculate the initial velocity of Dan
Using conservation of momentum
Put the value into the formula
Hence, The velocity of Dan is 1.13 m/s.
